Abstract

The hearing aid according to the invention comprises a skeleton, which comprises an outer support element, an inner support element and a connecting element and on which are arranged at least part of the electronic components of the hearing aid. The two support elements essentially form the end faces (IS,AS) of an irregular frustum.
To the support elements is fixed a microporous diaphragm in such a way that it essentially forms the circumferential surface of the frustum. The microporous diaphragm and the skeleton together form a substantially tubular moulding cavity, in which a shaped member adapted to the individual auditory canal is moulded with a hardening moulding material in the ear of the user. Prior to the moulding process the skeleton can be roughly adapted to the individual auditory canal by a corresponding deformation of the connecting element. The microporous diaphragm is preferably not only gas permeable perpendicular to its main faces but also parallel to these faces, is impermeable for the liquid or paste-like moulding material used for moulding the shaped member, and is preferably also water and oil-repellent at least on the outside of the hearing aid.
